We obtained an optical spectrum of TCP J01375892+4951055 (see CBAT TOCP) with the FRODOSpec spectrograph (Barnsley et al. 2012) on the 2.0m Liverpool Telescope (Steele et al. 2004) on 2016 October 20.06 UT. The spectrum was taken using the lower resolution mode of FRODOSpec, which gives a wavelength coverage of 3900 to 5700 Å and 5800 to 9400 Å, with a resolution of R ~ 2400.
The spectrum shows absorption from Hα - Hε, along with a detection of He I (4471 Å) absorption. There are no clear emission components to any of these these lines.
This spectrum is consistent with TCP J01375892+4951055 being an outburst of a Galactic dwarf nova in the constellation of Andromeda.
